Answer:
Groupthink
Step-by-step explanation:
Groupthink is a term first used in 1972 by social psychologist Irving L. Janis.
It is about a psychological phenomenon in which people want a consensus within a group by just being in agreement. In many cases, people will set aside their own personal beliefs or adopt the opinion of the rest of the group.
